We often don’t think about the effects that relative humidity can have. It doesn’t stand out the way that the temperature of a room does, where a person might have to turn on a fan or turn up a heater. In fact, relative humidity is crucial to promoting good indoor air quality and is important to the health and safety of several different applications and areas.
As weather gets cooler, it’s a common misconception that cold and flu viruses are more frequent due to the temperatures outside. This can actually be attributed to the fact that we are inside more, thus being exposed to higher concentrations of pollutants. Poor indoor air quality can cause what has come to be known as sick building syndrome.
As students are returning to schools and office buildings are being reopened, it’s important to consider the safety of the buildings after extensive closures. Proper precautions need to be taken to ensure building readiness, which introduces a critical question:
How do you return the HVAC system back to normal operations (and continued operations)? Continue reading “Back to School: Precautions for Building Readiness”
The Series GSTA carbon monoxide/nitrogen dioxide gas transmitters offer a robust, low cost alternative to standalone garage ventilation control packages.
As cities around the world continue to grow, the need for parking becomes an integral part of new commercial and municipal building plans. Many building designers are finding ways to offer adequate parking in a limited amount of real estate. Two emerging trends to do so are enclosed parking garages and mixed-use parking garages. Both of these designs seek to offer users a comfortable way to park their vehicles, all while being near their final destination. This means that the parking facility and the commercial or residential buildings are not separated, but are integrated together into one building structure. Due to this integration, two major concerns arise. How do we ventilate the harmful exhaust from the vehicles while being so close to the populated areas of the building, which require clean air and how do we accomplish this in the most energy efficient way possible? The Dwyer® Series GSTA carbon monoxide/nitrogen dioxide gas transmitters offer the sensory inputs necessary for any building automation system to answer this very quandary in an efficient and low cost manner.

ASHRAE 62.1 Standard for Ventilation for Acceptable Indoor Air Quality provides recommendations for minimum ventilation rates and other parameters to ensure good indoor air quality (IAQ). Keeping the IAQ at a safe level will help to minimize any adverse health effects caused by air quality factors.
The 62.1 standard is intended for both new building and building addition projects. It can also be used as a guide for the improvement of IAQ in existing buildings.
In order to properly conform to the ASHRAE 62.1 standard, it is necessary for sensors to be both stable and accurate. Continue reading “How is Stability Related to ASHRAE 62.1 Standards?”
